I should mention that a couple of the brewclub members (and the pone hosting the party) have Mexican brides, so this won't be an easy crowd to fool.

I perused the wiki on Mexican beer and seems some of the better commercial stuff is in the Vienna to Dunkel category. I think I'll brew one of those, and maybe a pilsner too. I like the idea of making a cocktail of beer, lime juice, and chili powder.
